'Beer goggles' effect explained
BBC News

"Scientists believe they have worked out a formula to calculate how "beer goggles" affect a drinker's vision."

"The drink-fuelled phenomenon is said to transform supposedly "ugly" people into beauties - until the morning after."

"The research was commissioned by eyecare firm Bausch & Lomb PureVision."

How is Bausch & Lomb going to use this knowledge?
